Powermaster pedal vs vacuum brake pedal

[Steve Wood]

Do I remember correctly that the pivot point on the vacuum pedal is about half an inch above the location for the PM pedal....so that the vacuum pedal gives more leverage?

I converted my car to vacuum quite a while ago and remember modifying the powermaster pedal to get it to work. The pivot point for the vacuum is roughly 1/2" or so higher than the powermaster, so you have a good memory

Looks like my memory sux

They say the second thing to go is the mind.....   


With the clevis point being higher, does the power master enter the car at more of a downward angle, or does GM just let there be an angle involved ?

IIRC there is an intermediate (angle creating) bracket twix firewall and P-Master

PM does have a bracket, don't recall if it had an angle, or not.   And, they are correct, Earl
